【摘要】：目的了解济南市流感流行特征及优势毒株的分布,为防制工作提供科学依据。方法对济南市流感样病例监测资料、病原学监测结果和暴发疫情资料进行描述性分析。结果 2009-2013年济南市4所哨点医院报告流感样病例33 489例,平均就诊百分比为1.34%(0.93%~2.58%),以2009年最高(2.58%)。0~4岁组流感样病例占报告总数的60.00%,5~14岁组占17.93%。病例流感病毒核酸检测阳性率为22.55%,以新甲型H1N1、B型和H3N2居多;2009年阳性率最高为48.54%,其次为2012年34.02%。2009年10-12月和2013年1月病毒型别以新甲型H1N1为主,2009年9-11月以H3N2为主,2010-2012年1-3、12月以B型为主。共报告暴发疫情43起,其中2009年38起;发生地以中学、中职学校(17起)和小学为主(15起)。结论济南市流感样病例就诊百分比较平稳,有春季和冬季2个高峰,病例以小年龄组居多。不同年度流感病毒优势毒株有变化。暴发疫情主要发生在中小学及大中专院校。
[Abstract]:Objective to understand the epidemic characteristics of influenza and the distribution of dominant strains in Jinan City, and to provide scientific basis for the prevention and control of influenza cases. Results 33,489 influenza-like cases were reported in 4 sentinel hospitals in Jinan from 2009 to 2013. The average percentage of visits was 1. 34 / 0. 93% and 2. 58% respectively. In 2009, the highest number of influenza cases in the 4-year-old group was 2. 58%, accounting for 60.00% of the total number of reported influenza-like cases. The positive rate of influenza virus nucleic acid detection was 22.55 in the group of 14 years old, most of which were new type A H1N1 1B and H3N2; In 2009, the highest positive rate was 48.54, followed by 34.022.The virus type in October to December 2009 and January 2013 was mainly new A (H1N1). From September to November in 2009, H3N2 was the main type in 2010-2012 and B type in December. A total of 43 outbreaks were reported, of which 38 were reported on 2009.

【正文快照】： 流感是由流感病毒引起的急性呼吸道传染病。由于流感病毒致病力强,易发生变异,若人群对变异株缺乏免疫力,易引起暴发流行[1]。流感监测能及早发现变异株,是进行流感疫情预测和预警的基础,为预防与控制流感流行提供重要依据[2]。本文将济南市2009-2013年间的哨点医院流感病例及
